UPDATE 1-Explosion kills Kenyan policeman in Dadaab camp

* Several attacks in area since Kenya sent troops into
Somalia
(Adds detail, background)

GARISSA, Kenya Dec 5 (Reuters) - An explosion killed
one Kenyan police officer and wounded three on Monday at the
Dadaab refugee complex in the north of the country near Somalia,
provincial police commander Leo Nyongesa said.

He said the blast occurred in the Ifo refugee camp, part of
the Dadaab facility in North Eastern province that is home to
more than 400,000 Somalis. The Kenya Red Cross confirmed the
casualties.

The officers were in a convoy of police cars escorting
United Nations officials to the camp. The blast took place when
they stepped out of their car, Nyongesa said.

Kenya sent troops across the border into Somalia in October
to crush the al Qaeda-affiliated al Shabaab rebels it blames for
attacks on its security forces and tourists inside Kenya, and
the kidnap of two Spanish aid workers from Dadaab.

Since then, there has been a string of attacks in the area.
A remote-controlled bomb hit a police car in another part of the
Dadaab complex on Nov. 15 and on Nov. 5 a U.N. convoy struck a
bomb buried in the camp, but it did not explode.

The attacks in Dadaab, coupled with the kidnappings in
October, have forced a number of aid agencies to scale back
staff numbers, hitting the provision of aid to those living in
the world's biggest refugee camp.
